PandaPrint

This is a server that enables uploading from OrcaSlicer to Bambu Lab printers in LAN mode without the use of the Bambu Lab network plugin.

Users concerned about security or software freedom may be reluctant to use either the Bambu Lab cloud service or the proprietary Bambu Lab network plugin. PandaPrint does not replace all of the functionality in the network plugin, but it does allow sending a project to a printer directly from OrcaSlicer.

Configuration

Create a printers.yaml file like this example:

printers:
  - name: bambu
    host: bambu.lan
    serial: 123456789012345
    key: 12345678

The fields are as follows:

name: A friendly name of your choosing. This will appear in the

url supplied to OrcaSlicer later. If you have more than one printer, ensure this is unique.

host: The hostname or IP address of the printer.

serial: The serial number of the printer.

key: The access key for the printer. Get this from the LAN mode

screen.

The following fields are optional and are used to configure printing options when "Upload and Print" is used from the slicer. They have no effect for files that are merely uploaded.

timelapse: Enable timelapse video (true/false).

bed_levelling: Perform bed levelling (true/false).

flow_cali: Perform flow calibration (true/false).

vibration_cali: Perform vibration calibration (true/false).

layer_inspect: Enable layer inspection (true/false).

use_ams: Use the AMS instead of the external spool (true/false).

No AMS mapping is performed, so be sure that the spool numbers in the slicer match the actual contents of the AMS when using "Upload and Print".

Running

The easiest way to run this is from a container image.

Running the Container Image

A sample docker-compose file is included.

docker compose up -d

Running from Source

To run this directly from the source repo:

poetry install
poetry run pandaprint ./printers.yaml

Configuring OrcaSlicer

1. Edit the printer.
2. Enable the Advanced toggle.
3. Under Basic information, Advanced, check Use 3rd-party print host
4. Close the printer edit dialog.
5. Click the Connection button (wifi icon) next to the printer.
6. Under Print Host uplod set the following: Host Type: Octo/Klipper Hostname, IP or URL: http://localhost:8080/bambu (if you chose something other than bambu as the name in printers.yaml, use that here instead)
7. Press the Test button to ensure everything is working.
8. Press "OK"

At this point, you should be able to use the Print Plate button to send projects to the printer.
